Domain Mapping of Product Service System Oriented on CNC Machine Tools

Abstract

Product service system is the organic combination of product and services to adapt to the development needs of service-based society. The mapping between requirement domain, function domain, technology domain is an important approach for transferring customer requirements in the development process of product service system. Firstly, this paper determines the composition of requirement domain, function domain and technology domain, and constructs a model of mapping relationship and method between domains. Then, determining the weights of customer requirements based on RAHP (Rough Analytic Hierarchy Process), this paper constructs the requirement-function HoQ (House of Quality) and the function-technology HoQ based on the theory of Quality Function Deployment, completes the consistency test based on relevant analysis, and improves the quality target value of HoQ. Finally, this paper builds an integrated architecture of product service system based on relevance recognition between product modules and service modules. Taking ETC (Economic Turning Center) series CNC (Computer Numerical Control) machine tools as an example, the proposed method in this paper is verified.
